The gastric acid barrier, an important host defence against small bowel infection, may be compromised by infection with Helicobacter pylori.
In developing countries, H. pylori infection occurs early in life and prevalence of hypochlorhydria is high particularly in the malnourished, which may predispose a child to repeated gastrointestinal infection and diarrhoea.
Diarrhoea being a leading cause of childhood mortality and morbidity in developing countries, we investigated the prevalence of H. pylori infection in children in a poor Bangladeshi community and explored its association with socioeconomic and nutritional status.
The study was conducted in a poor periurban community among 469 children aged 1-99 months.
Parents were interviewed using a questionnaire.
To detect active infection with H. pylori a 13C-urea breath test was performed and weight was recorded on a beam balance with a sensitivity of 20 g. Results.
In all, 61% of 36 infants aged 1-3 months were positive for H. pylori ; this rate dropped steadily with increasing age and was 33% in 10-15 month old children and then rose to 84% in 6-9 year olds.
Overall H. pylori infection had no association with nutritional state of the child, or family income but the infection rate was 2.5 times higher in children of mothers with no schooling.
The H. pylori infection rate is very high in early infancy in a poor periurban community of Bangladesh. (...)
